Zoom from Fig. 2 towards W43-MM3, with the same colour code as in Fig. 4 except for the high-velocity integration of CO (in red contours) which is 125.9–133.6 km s⁻¹ instead of 119.6–127.2 km s⁻¹. Contours are 4, 10 to Max by steps of 10 in units of σ_HV3 = 13 mJy beam⁻¹ km s⁻¹ at high velocity and 5, 15 to Max by steps of 15 in units of σ_LV3 = 5 mJy beam⁻¹ km s⁻¹ at low velocity. Same convention as in Fig. 4 for lines and ellipses. An additional zoomed-in figure highlighting outflows from cores #3 and #244 is provided in Fig. E.2b.
